A new approach for the analysis of the efficiency and linearity of Chireix-outphasing combiners is presented. The approach takes into account, in an explicit manner, the effect of impedance mismatch… (More)

Nonlinearities in linear amplification with nonlinear components (LINC) amplifiers using Chireix-outphasing combiners are studied and their sources are identified. A generalized analytical approach… (More)

A design methodology for the distributed microelectromechanical system (MEMS) impedance matching networks based on the optimization of the uniformity of the Smith chart coverage has been developed.… (More)

An analytical design methodology of outphasing amplification systems is proposed using new simplified analytical expressions for the instantaneous efficiency and the input/output voltages of Chireix… (More)

This paper proposes a new amplifier architecture based on the outphasing technique intended for the efficiency enhancement of linear amplification with nonlinear components (LINC) transmitters. The… (More)

A new approach for studying the combiner efficiency in a LINC amplifier based on analytical expressions of the instantaneous combiner efficiency and the signal's probability distribution function… (More)

We first present the design, fabrication and test of a voltage controlled variable attenuator and a voltage controlled variable phase shifter. The designs use a reflection-type topology with PIN… (More)

Emerging intelligent and reconfigurable radiofrequency front-ends require the use of embedded vector measurements to ensure their proper tuning and operation at the frequency of choice. Alternative… (More)

Ad hoc networks offer many excellent prospects as a complementary technology to the traditional cellular networks. Nonetheless, some problems still slow down their deployment on a large scale. One of… (More)
